Therefore, the specific circuit control relationships and circuit connections of the present utility model will not be described in detail.

[0026] As Figures 1 - 5 shown, the present utility model provides an embodiment of a two-way anti-loosening installation electromagnetic lock device.

[0027] The two-way anti-loosening installation electromagnetic lock device means that the installation method of the electromagnetic lock device includes hanging installation and side installation, and both installations can prevent the bolts from loosening. The electromagnetic lock device includes a lock body 1 installed on the door frame or the door. The lock body 1 is provided with an installation mating surface 11 for hanging installation or side installation. The installation mating surface is provided with an installation hole 13. The lock body 1 is at least provided with a fixing groove 12. The installation hole 13 is arranged in the fixing groove 12. A fixing structure 2 for anti-loosening is arranged in the fixing groove 12. The fixing structure 2 is provided with a through hole 21 and a fastener (not marked in the drawing) arranged in the through hole 21. After installation, the fastener passes through the through hole 21 and cooperates with a fixing hole 14 arranged in the fixing groove 12 to fix the fixing structure 2 and the lock body 1, and the fixing structure 2 abuts against the end of the fastener on the installation hole 13.

[0028] Specifically, the fastener includes bolts and the like. The number of the fixing grooves 12 is two, which are respectively arranged at both ends of the lock body 1. The fixing groove 12 opens outward with an increasing opening in the fixing direction, which can avoid the occurrence of reverse drawing die during manufacturing and reduce the manufacturing difficulty.

[0029] For the sake of convenience in description, this embodiment is described by taking a two-piece fixing structure as an example. The mounting holes 13 include four, which are divided into two groups, with two in each group, and are arranged to penetrate the mounting mating surface 11 in the fixing groove 12.

[0030] The fixing groove 12 has openings on one or two surfaces of the lock body. When there is an opening in one direction, the fixing hole 14 is arranged in the same direction as the mounting hole 13. When there are openings in two directions, the fixing hole 14 can be arranged in a direction different from that of the mounting hole 13. For example, the mounting hole 13 and the fixing hole 14 are perpendicular, as Figure 4 shown. In this way, the fastening directions of the fasteners for respectively fixing the lock body 1 and the fasteners for fixing the fixing structure 2 to the fixed lock body 1 can be different. When the fixing structure 2 abuts against the fasteners after being fixed, it can prevent the fasteners for fixing the lock body 1 from loosening during frequent opening and closing.

[0031] A receiving cavity (not marked in the drawing) is provided in the lock body 1. A coil 16 and a magnetic core 17 that moves when powered on or off are provided in the receiving cavity. One end of the magnetic core 17 is connected to one end of a transmission member 18, and the other end of the transmission member 18 is connected to a toggle lever 19. The toggle lever 19 is movably connected to the lock body 1 through a rotating shaft. A locking tongue 15 is provided at the toggling end of the toggle lever 19. Specifically, the coil 16 and the locking tongue 15 are fixed on a fixing plate 10. During installation, the coil 16 and the locking tongue 15 are received in the receiving cavity, and a lock hole through which the locking tongue 15 can protrude is provided on the lock body 1. During operation, when the coil 16 is powered on, the magnetic core 17 moves, thereby driving the transmission member 18 to move. The toggle lever 19 connected to one end of the transmission member 18 rotates around the rotating shaft 110 accordingly, and the toggle lever 19 drives the locking tongue 15 to perform a telescopic movement. As required, a limiting structure (not marked in the drawing) is provided on the side wall of the fixing groove 12 in the loosening direction of the lock body. The limiting structure includes a limiting groove 121. A protrusion (not marked in the drawing) that cooperates with the position groove is provided on the side surface of the fixing structure 2. During installation, the fixing structure 2 is placed in the fixing groove 12 from a direction perpendicular to the installation direction of the mounting hole 13. The fixing hole 14 for fixing the fixing structure 2 is not in the same plane as the mounting hole 13, such as being provided on the side surface, as Figure 4 shown.

[0032] The fixing structure 2 includes a fixing block. Two stop strips 22 are provided on the end face of the fixing block close to the mounting hole 13, and a gap is provided between the two stop strips 22. An inclined surface is provided on the end face of each stop strip 22, and the directions of the two inclined surfaces are opposite, so that a groove-like structure is formed on the end faces of the two stop strips 22.

[0033] When fixing, the installation mating surface of the lock body is fixed to the door frame or the door through fasteners such as bolts. Then, the fixing structure is placed in the fixing groove, and the fixing structure is fixed to the lock body through fasteners such as bolts, so that the end of the fixing structure abuts against the fastener of the lock body. Since the fixing structure is formed by being fixed to the lock body, and this fixing structure abuts against the fastener for fixedly installing the lock body, no force will be generated on the fixing structure when opening and closing the door. This fixing structure avoids loosening during frequent opening and closing processes, improving the fastening of installation and the reliability of use. At the same time, since the lock body can be installed in a hanging manner or a side-mounted manner, the installation requirements are reduced.

[0034] As Figure 5 shown, the present utility model further provides a two-way anti-loosening installation electromagnetic lock device, which can be installed in cooperation with a door. The two-way anti-loosening installation electromagnetic lock device further includes a fixed installation structure 3. The fixed installation structure includes a fixing plate 30 and a connecting rod 31 connected to the fixing plate. The connecting rod 31 is provided with a fixing hole (not marked in the drawing). When fixing, the connecting rod 31 on the fixed installation structure 3 is passed through the through hole on the door, and the end of the connecting rod 31 corresponds to the installation hole 13 on the lock body 1, and the lock body is fixed to the door through fasteners.

[0035] As required, when the lock body 1 is provided with an electromagnetic coil, it can be installed by hanging on the door frame, and the side of the electromagnetic coil generating magnetic force is attracted to the magnet fixed on the door to achieve fixation. When installed on the side, the anti-loosening electromagnetic lock device further includes a movable assembly that generates magnetic force under the action of the electromagnetic coil to lock or unlock.

[0036] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
